Hovenweep National Monument

This June 21, 2004 image taken at Hovenweep National Monument shows a spiral petroglph illuminated shortly after sunrise on the summer solstice. Not unlike possible sun watching stations in Chaco Canyon, this example indicates that ancestral Puebloans may have taken advantage of natural solar markers, carving designs to mark the seasons.
